PG - 1830-4 AB - Interleukin-18 (IL-18) is a newly described cytokine, formerly called interferon-gamma (IFN-gamma)-inducing factor. In a simple 24-h human whole blood culture, IFN-gamma was produced by the combination of lipopolysaccharide (LPS) plus IL-18. To liberate cytokines in the leukocyte and red cell compartments, the detergent Triton X-100 was added to the entire blood culture. The combination of low concentrations of LPS plus IL-18 induced a 3- to 5-fold greater production of IFN-gamma than did either stimulant alone. Tumor necrosis factor-alpha (TNF-alpha), IL-6, and IL-8 were also produced. The presence of IL-10 completely suppressed the production of IFN-gamma and reduced that of TNF-alpha, IL-6, and IL-8. Thus, IFN-gamma, TNF-alpha, IL-8, and IL-6 are produced in a single whole blood culture, making correlations in the synthesis of a T helper type 1 cytokine and proinflammatory cytokines with disease activity possible in a single culture.
